A Russian missile strike killed four people and hit a hospital in eastern Ukraine, officials said on Monday (May 15), as President Volodymyr Zelenskyy won the promise of “hundreds” more missiles and drones on a visit to Britain.

The attack on the front-line city of Avdiivka was one of a wave of strikes that damaged 57 residential buildings in 13 localities, Ukraine’s national police force said.

“Four people died as a result of a missile attack on Avdiivka. Russians attacked the city with missiles this morning, hitting a hospital,” Donetsk regional governor Pavlo Kyrylenko said.

But elsewhere, Ukraine claimed advances around Bakhmut, as its armed forces prepare for a counter-offensive over a year on from the invasion ordered by Russian President Vladimir Putin in February 2022.
